Application filed September 28, 1912. Serial 310. 721,961.

following is a full, clear, and accurate specification of our preferredconstruction, being suchas will enable others to make and use the samewith absolute exactitude.

Our invention relates, in its broadest scope, to the baling ofcompressible material by an automatic organism wherein the severalelements coact in harmonious accord so that the whole may be under thecontrol and subject to the volition of a single operator.

This invention has for its main object the compression, and wiring, ofhay, straw, cotton, or other compressible products, which,

hereinafter we will designate as the material, in securing the wiresaround the bales of material by ties or knots having a limited degreeofyieldability, performing said results in a more certain and perfectmanner and with greater rapidity than has heretofore been done bymachines of this general character. v

Perhaps the most important slngle feature and the specific object of ourinvention is the means for securing together ofthe two ends of a singlewire into a yieldable knot or tie, and accomplishing the same while thewire is under a superstraln or an excess tension.

Other objects and particular advantages of our invention will be broughtout in the course of the following specification.

The details of the invention and the manner of operation of thedifferent mechanisms will be fully set forth hereinafter and the novelfeatures thereof will be recited in the claims.

The preferred manner for the construction and the arrangement of theseveral parts, devices, and mechanisms are fully shown in theaccompanying drawings forming part of this specification, in whichFigure 1 is a side elevation of the front portion of our machine. Fig. 2is a top plan view of the central portion of our machine. Fig. 3 is afront elevation of one of the three twisters.

Similar indices denote like parts throughout the several views of thedrawings.

In order that the construction and the operation of our invention may be'fully understood and that its several advantages may be fullyappreciated we will now take 'up a detailed description thereof in whichwe will set forth the same as briefly and as comprehensively as we maybe able to do.

The body of our invention comprises a framework consisting, primarily,of the four horizontal sills spaced apart forming a square in crosssection, between the central portions of which is formed the compressionchamber, in which the bales A are formed. Said sills comprise two, upperand lower, on the right-hand side, which are desig: nated 1 and. 1respectively; and the two located on the left-hand side which aredenoted by indices 2 and 2. i

A compression-chamber is formed in the central portion of the machine,as stated, in which chamber reciprocates the plunger 3. Secured on theface of the plunger is the needle block 4, through which the needlesoperate -as hereinafter set forth. The plunger 3 is moved to and fro bythe pitman 5 which has its rear end pivoted therein. The forward end ofsaid pitman 5 is hinged to the rear end of the link or auxiliary pitman6 by means of the pivot 7. The forward end of the link 6 is carried by awrist mounted on the crank-shaft 8. However various means may beemployed for operating the piston and we make no claim to such means inthis application. Extending across below the frame, slightly rearward ofcrank-shaft 8, is the shaft 9 which is carriedby brackets 10 extendingdown below the frame as indicated and for the purpose stated.

. A, therefore we employ three needles B,'.

Pivoted at one end on shaft 9, with its other end mounted to pivot 7, isthe arm 11. Secured on shaft 8 is the large gearwheel 12. Supported infront of shaft 8 is shaft 13 on which is secured the intermediategear-wheel 14. Mounted on brackets extending up from the frame is theshaft 15 on which is secured the drive-wheel 16. A pinion L is securedon shaft 13 and it meshes with the gear-wheel 12; and a pinion N issecured on shaft 15 and it meshes with the said gear-wheel 14.

Extending across below the frame, in front of the compression-chamber,is shaft 17 which projects at each end beyond the frame. Secured on theends of shaft 17 are the cranks 18 and 18- Extending rearward from saidcranks are the adjustable connecting rods 19 and 19, respectively. Therear ends of said connecting rods are mounted to the respective pivots22 and 22, which latter are carried by the lower ends of. the respectiveswinging-arms 20 and 20', the upper ends of said arms being mounted onthe respective pivots 21 and 21'. Said pivots 21 and 21 are eachcarriedby a bracket secured to the sides of the frame, said brackets beingdesignated 90 and 90, respectively. In this instance we propose to placethree binding-wires around the bale C and D, which are curvedsubstantially as shown, same being adapted to operate through therespective slots 6, c and d of the block 4. Secured on the twoprojecting portiOns of shaft 17, adjoining the cranks 18 and 18, are therespective sprocket-wheels 27 and 27 each of which is connected by asprocket-chain, 28 and 28 respectively, to sprocket-wheels which aresecured on the projecting ends of-the crank-shaft 8, as for instance thewheel 29 as shown in Fig. 1, the other not appearing in the drawings.For operating the said needles we provide a swinging-frame, shown inFig. 17. Extending across underneath the compression chamber, and ri 61secured to said swinging arms 20-an 20 are the upper and the lowerangle-bars 23 and 23', respectively. The base or butt ends of theneedles are all rigidly secured to the bar 23 by the bolts 25, 25' Somedistance from their bases the three needles are connected by the strutand-stay rod 30, which holds them the fproper distances apart andprevents them rom swinging laterally. Said rod 30 is connected. to theangle-bar 23 by two braces 31 and 31.

By the above arrangement it is apparent that as the arms 20 and 20 swingbackward and forward the points of the needles will be moved downwardand upward, respectively, through said slots 7), c and d.

Suspended from the underside of the frame, in the rear of shaft 17, isthe freesha'ft 24 on which is mounted the three spools 26, 26 and 26".On each of said spools is to be wound a supply of wire, as the wire Eshown in Fig. 7, and elsewhere. Extending across and mounted on theunderside of the frame, at about the rear end of thecompression-chamber, is the idle shaft 32. Secured on shaft 32, with asegment of its periphery projecting up throu h a slot in the floor ofthe compression-chamber, is the spur-wheel 33 which engages theunderside of the bales A'as they are being formed,

thereby revolving said shaft 32. Mounted 011 top of the frame, over thefront end of the compression chamber is the brackets 34 and 34 in whichis mounted the main twister-shaft '35, and secured on the rojecting endsof shaft 35 are the sproc etwheels 36 and 36, by which itis moved.Rigidly mounted on shaft 17 are the two sprocket-wheels 37 and 37, whichcorrespond with the respective wheels 36 and 36'. Connectingsprocket-wheel 37 with sprocket wheel 36 is the sprocket chain 38; andlikewise connecting the corresponding sprocket wheels on the other sideof the machine is the chain 38. A clutch is provided on each side of themachine, and as the two are identical with each other a description ofone will answer for both: Said clutches are located between the opposingfaces of each set of sprockets 27 and 37, as shown in Figs.' 11, 12 and13, the former showing the inner face of the part carried bysprocket-wheel '27, and the latter the inner face of the parts carriedby sprocket-wheel 37, while the other view shows in section all theparts of the clutch combined in operative position. Each-clutch consistsof the dog 39 having an outwardly extending finger F extending beyondthe periphery of the clutch proper, as in Fig. 13. Said dog has ahorlzontal oblong aperture G therethrough which loosely surrounds theshaft 17 Said dog is mounted by pivot 40 whereby it may swing, withinthe limits of the slot G. Extending out in an axial direction from theinner face of the dog 39 is the lug H. Extending from the face of thesprocket-wheel 27 and located near the periphery thereof is the roller41 which is adapted to engage the lug H when the dog 39 swings in onedirection and to be free therefrom when the dog swings in the oppositedirection. The dog 39 is returned to its normal position, with relationto sprocket-wheel 37, by the helical spring 42, one end of said springbeing attached to sprocket-wheel37 and the other to the dog 39, asindicated. Secured on each end of shaft 32 is a cam, as cams 43 and 43.Extending along near the lower sills of the frame is the bars 44 and44', same being pivotally secured near their centers by the respectivehangers 45 and 45'. The rear ends of said bars 4444 are adapted to beimpinged by the cams 43 and 43 at each revo lution of the wheel 33, tocause the forward ends of said bars to be raised. When not so raisedthen the forward ends of said bars are lowered where they will beengaged by finger F of dogs 39. The forward ends of bars 4444 areadapted to be returned to engage the fingers F by means of the helicalspring 46, as shown.

Twister mechanism.Spaced a proper distance apart and secured on shaft 35are the three dished cam or twister-wheels 47, 48 and 49, which areduplicates of each other, the faces thereof being directed to the left,as shown in Fig. 7. Formed on a portion of the rim of each of saidtwisterwheels is a gear I which extends only a portion of the distancetherearound to g), and it adjoins the periphery thereof. When referringfurther to the twister-wheels we will mention the one indicated bynumeral 49 and this of course will answer for all. Also as there arethree twister mechanisms operated by the respective twister-wheels andas they are all duplicatesof each other in construction and operation,therefore to simplify the description we will refer to correspondingparts of the three by like indices, and a description of one will ofcourse answer for all. Extending across the top of the front end of thecompression-chamber is a platform 50 on which the three twistermechanisms are secured, same being spaced according to the saidtwister-wheels.

Each of the twisters includes a substantial angular casting or base 51,which, together with the twisters in detail, is shown in Figs. 3, 4, 5,and 6, the projections of said castings 51 being toward the front end ofthe by the screw j, and extending thereabove, is

machine, as shown in Fig. 7. Formed integral with the base 51 is thehead thereof,

' perpendicular.

perpendicular, is the core 53 which is adjustable and it is round incross section, and it is secured in place by the set-screw 59.

Revolubly mounted on the upper extension of the core 53, with its upperface even with the upper end thereof and its lower face resting on thetop of the head 52, .is a spool-shaped member, comprising an upper orcinch-disk 54, and the lower or cutterdisk 55, the two being spacedapart but integrally connected by the body or stem 56. Said spool-shapedmember is retained in place by the washer 57 and the screw 58, as shownin Fig. 4. Formed in the periphery ofthe disk 54 are a plurality ofsquare notches e which are spaced some distance apart; and likewise inthe periphery of the disk 55 an equal number of like notches f areformed, saine being in vertical alinement wit-h notches e. The peripheryof disk 54 forms a true circle, except for notches (3,1 while theperiphery of disk 55 is formed by straight lines extending between eachtwo of the notches f, as shown in Fig. 15.

Formed integral with and extending out from the left side of the head 52is the projection 60. Extending through projection 60 and parallel withthe core 53 is the bolt 61, to the upper end of which is secured theknife 62, shown in plan in Fig. 14. The bolt 61 forms the axle for theknife 62, allowing said knife to swing laterally. A notch g is formed inone side of the knife, same being located near the bolt 61 on which theknife swings. Formed across the top of casting 51, forward of head 52,is a barrel 63 (Fig. 6) in which slides the horizontal pintle 64, whichacts as a guide for the knife 62 and by which it is operated. The leftend of pintle 64 is pivoted to the knife by the screw 65. The rear endof the knife is retained, normally to the right by the helical spring66, one end of which is connected to the knife by the screw 67, whileits other end is secured to the casting 51 by the screw 68.

Numeral 69 denotes a plate which is secured at its rear to the top ofthe barrel 63 by the screws h and h. Said plate has two forwardlyextending fingers, 7c and 7c, the former extending over the disk 54 andthe latter, which is turned at right-angles to the former, extendsbetween the disks 54 and 55, both being located to the left of the core53 as shown in Fig. 5.

Secured to the side of the projection 60,

the bracket 70. Extending over the forward portion of knife 52 andpivoted to the top of bracket 70 by screw m (Fig. 5) is the cincher 71whose free or operating end extends around in front of the cinch-disk54,

same having a flat portion which extends in under the disk 54 and a headportion which extends oversaid disk, as shown in Figs. 6 and 5,respectively. The lateral swinging movements of the cincher 71 may belimited and adjusted by the adjustingscrew 72, the latter being threadedthrough the bracket 70. Revolubly mounted on the lower extension of thecore 53 is the angular gear 73, the smaller end thereof being uppermost.Formed integral with the-lower end of gear 73 is the block 74, threesides of which are square the other being rounded. The lower face ofblock 74 is flush with the lower end of the core 53, there being a notch72 formed in one side thereof (Figs. 3, 8, 9). Extending down from block74, adjoining the side opposite to the rounded side of said block andintegral therewith, is the master hook 75, same being to one side of thecenter of said block, as shown in Fig. 4.

Numeral 7 6 designates a collar rotatably mounted on the lower extensionof the core 53, and located between the lower end of head 52 andtheupper end of the gear 73. Rotatably mounted in the core 53, to one sideof the center thereof, projecting up beyond collar 76 and down throughthe lower end of the core, is the stem 77. On the lower projection ofstem 77 is formed the minor hook 78. Extending out from stem 77 is afinger 79 (Fig. 4) there being a hole formed in the collar 7 6 in whichsaid finger may loosely operate, whereby as the collar is moved the stem77 will be turned, thereby turning the hook 78.

Numeral 80 denotes a finger extending out from collar 76 by which saidcollar may be moved. Connected to the finger 80 and attached, undertension, to the casting 51 is the spring 81 by which the hook 78 isresiliently returned to its normal position. Extending down from thelower end of the core 53, parallel with the stem 77, and located to oneside of the center of said core, is the twisterpin 82. The variousmovements of the twisters are each controlled by its cam ortwisterwheel, 47 48 or 49. The gear I for instance operating on the gear73 results in moving the gear 73 and the block 74 during only part ofthe time thetwister-wheel is making a revolution, and during this timethe gear 73 is being revolved then the hook 75 is carried aroundconcentric with the core 53, the

latter always remaining stationary.

Insuring the tooth 86 always meshing in one of the notches f, andpreventing turning of the disks 54 and 55 when said tooth is out ofcommission, we provide the straight edges on the periphery of the disk55 as shown in Fig. 15. Said straight edgesare adapted to slide oncontact with the surface j of the cam 87 as shown.

Near the point of each needle an eye as is formed therethrough in whichis revolubly mounted the two rollers 83 and .84, which are arrangedtandem with relation to each other,

each having a channel around in its periphery. The wire is adapted tofeed between said rollers traveling in'said channels thereof as shown. Ii

M odus 0peramiz'.Suppose now that the end of the wire which extends upfrom the spool 26", for instance, passing up the nee- (116, D andthrough,the eye m thereof, between the rollers 83 and 84, to the cincherend of the wire is being held by the cincher then the bale A is beingformed in the compression-chamber, the Wire of course being drawn fromsaid spool as the bale is formed,) the needle at this time bein down. Assoon as the bale is completed ,t e s ur-wheel 33 will have made itsrevolution t ereby bringing the cam 43 into engagement with the end ofbar 44, which will cause the other end of said bar to raise therebyreleasing the fin- 35 ger F and allowing the spring 42 to swing the dog39 to one side where it will be engaged by the lug H, where it will bein the path of the roller 41, thereby allowing said the sprocketwheel 27into a unit with sprocket;wheel 37. Now as sprocket-wheel 37 revolves itwill result in revolving the shaft 35 therewith, thereby turning thetwister wheel 49. twister-Wheel 49 is giving a partial revolution, thatis before the gear I has engaged the pinion 73, the needles are movingup to operative position as follows Simultaneous with the release offinger F the crank 18 will we be started to turn, as it is secured onshaft 17. Now as crank 18 turns it will manifestly draw the frame, thatis the angle-bars 23 and 23', toward the shaft 17, which of course willmove the needles up to the posi- 5 tion shown in Fig. 7, therebycarryinthe wire upward in two portions, same eing doubled upon itself overroller 83 and locatin one portionin front and the other he hind theneedle. As the needle reaches its 110 upward limit of movement then therear portion of the wire carried by the needle and that portion of thewire extending down from the cincher will be parallel with each other,both being disposed diagonally across 115 the pin 82 as in Fig. 3.Following the above the turning of wheel 49 will cause the cam 85 toengage the finger 80, turning the collar 76, thereby turning the hook 78and cans ing it to engage the-pin 82 below said double 2o portions ofwire which extend across the pin 82, forming an eye through which saiddouble portions of wire are disposed, as shown in Fig. 8, therebyholding the double Wire at that point.

Following the above operation the turn-' ing of wheel 49: will cause thetooth 86 (projecting from the ring 87) to engage in one of the notchesf, thereby turnin the disks 54 and55 the distance of v one note and dur-1 9 Where it is held as in Fig. 5, and while the 75 roller to engage thelug H thereby locking 90v During the time the 57 ing the balance of therevolution of Wheel 49 one of the flat faces of disk 55 will slide onthe edge of the ring 87 thereby preventing the said disks from beingturned except the distance between two notches during the entirerevolution of wheel 49, in this connection see Fig. 15. At this timethere are two portions of wire in one of said notches the portionpreviously cinched and the portion just placedntherein by the rear sideof the needle, as in Fig. 7. Therefore as the disks are turned the saidtwo portions of the wire in notch f will be carried around thereby andthey will then be engaged by the cincher, and in position to be engagedby the knife62, as shown in Fig. 3. As soon as said double portions ofthe Wire are secured by the cincher then the cam 88 will enga e thepintle 64, pressing it inward, and there y causing the knife 62 to closein shearing contact with the lower face of disk 55, which of course willsever the double wires. However it will be noticed that the cincher willcontinue to hold the wire which extends upward and forward through theneedle, as shown in Figs. 3 and 5, therefore as the disk has turned onespace it is evident that as the needle moves down it will cause the wireto slide through the eye 00, f

still leaving the end of a new ortion of wire still secure in thecincher. s soon as said out has been made then the needle starts to movedown, by the means which are apparent, and during the downward movementof the needle the twist or tie is being made as follows: The wireextending around the bale now has two ends projecting up through the eyeformed by the hook 78 and the pin 82, as in Fig. 8. At this time thegearI engages the gear-pinion 73 turning same around, preferably fourrevolutions. The revolving of pinion 73 will of course turn the hook 75around therewith, causing the angular shoulder of said hook 75 to engagesaid double, now free, portions of the wire, causing them to slide downinto the curved portion of the hook, as in Fig. 9, and then as the hook75 continues to revolve it is apparent that said double free portions ofthe Wire will be carried around and around the double portions of thewire below the hook 78, thereby forming the loop E and the twist E", asshown in Fig. 20. As soon as the four twists have been made by hook 75the gear 1 will leave the pinion 73, allowing the fiat or straight sideof the block 74 to slide on the face of cam 89 thereby holding the hook75 in its at rest positlon which is that shown in Fig. 3 or in Fig. 4.Simultaneous with hook 75 attaining its at rest position the cam 85 willrelease finger 80 and allow the spring 81 to bring the collar back to atrest position, thereby swinging the hook .78 away from pin 82, as inFig. 3. As the hooks 75 and 78 attain their at rest positions it will beseen that the knot or tie shown in Fig. 20 will then be free to slidedownward away from pin 82, at which time the completed bale A is beingejected ready for a new one to be formed. As the pressure of the machineis released from the bale then the strain will be transferred to thebinding wires, and great strain will be exerted upon the tie just formedWhich will cause it to yield to a certain extent and finally assume theform of the tie E shown in Fig. 21.

Indice E denotes the waste portion of wire which is formed each time atie is made, said waste portion being formed by the 'cincher from thewire which extends over from one to another of the notches e.

We desire that it be understood that various changes may be .made in theseveral details of the construction without in any way departing fromthe spirit of our invention and without sacrificing any of theadvantages thereof.
